Evaluation of Australian undergraduate engineering management education for flexible delivery

This thesis examines issues in Australian undergraduate engineering management studies in the context of flexible learning delivery. It is proposed that, within an Australian context: a) the management skills and competencies required by graduate engineers can be determined and classified on a rational basis, permitting an educational focus on those elements most appropriate for graduates; and b) on-line and other computer-based technologies are a practical and effective method for the support of undergraduate engineering management studies. The doctoral project incorporates: • an examination of the nature of engineering management; • a review of the relevant literature establishing the importance of management studies in undergraduate engineering courses; • a review of historical and recent developments in Australian undergraduate engineering management studies; • an investigation of the management skills and competencies required by graduate engineers - based on original research; • an examination of flexible delivery of engineering education - based on professional practice experience; and • an evaluation of case studies of flexible delivery of engineering management education - based on original research and professional practice experience. A framework of ranked classified management skills is developed. Broadly, the ranking framework is generic professional skills, followed by general management skills and technical discipline specific management skills, followed by other professional discipline skills and theoretical skills. This framework provides a rational basis for design of undergraduate engineering management studies. This is supplemented by consideration of the management skills required for the future of engineering practice. It is concluded that undergraduate engineering management education is well suited to delivery and support by on-line and computer-based technology. Recent developments in improved access to the Internet, software systems for on-line collaboration and changes in copyright legislation to create a broad-based right to communication via on-line media have contributed to the facilitation of on-line delivery of teaching and learning. It is noted that though many on-line infrastructure issues have been satisfactorily resolved, higher level issues will emerge as being crucial, including the academic staff development and reward for operating in an online teaching environment and the financial sustainability of on-line development and delivery of courses.

Where and when to revegetate : a quantitative method for scheduling landscape reconstruction

Restoration of native vegetation is required in many regions of the world, but determining priority locations for revegetation is a complex problem. We consider the problem of determining spatial and temporal priorities for revegetation to maximize habitat for 62 bird species within a heavily cleared agricultural region, 11 000 km2 in area. We show how a reserve-selection framework can be applied to a complex, large-scale restoration-planning problem to account for multi-species objectives and connectivity requirements at a spatial extent and resolution relevant to management. Our approach explicitly accounts for time lags in planting and development of habitat resources, which is intended to avoid future population bottlenecks caused by delayed provision of critical resources, such as tree hollows. We coupled species-specific models of expected habitat quality and fragmentation effects with the dynamics of habitat suitability following replanting to produce species-specific maps for future times. Spatial priorities for restoration were determined by ranking locations (150-m grid cells) by their expected contribution to species habitat through time using the conservation planning tool, ‘‘Zonation.’’ We evaluated solutions by calculating expected trajectories of habitat availability for each species. We produced a spatially explicit revegetation schedule for the region that resulted in a balanced increase in habitat for all species. Priority areas for revegetation generally were clustered around existing vegetation, although not always. Areas on richer soils and with high rainfall were more highly ranked, reflecting their potential to support high-quality habitats that have been disproportionately cleared for agriculture. Accounting for delayed development of habitat resources altered the rank-order of locations in the derived revegetation plan and led to improved expected outcomes for fragmentation-sensitive species. This work demonstrates the potential for systematic restoration planning at large scales that accounts for multiple objectives, which is urgently needed by land and natural resource managers.

Determinants of Central bank independence and governance : problems and policy implications

Central bank independence and governance (CBIG) is a term subject to conflicting definitions and so its related studies are difficult to compare. This paper therefore focuses on developing of a more useable definition, and an index model identifying the determinants of independence and governance and their possible policy implications. It also examines various independence measurement tools such as ranking and index. The index model resulting centres on key central bank independence and corporate governance issues, such as, legal aspects, political aspects, price stability objective aspects, exchange rate policy aspects, monetary policy and deficit financing aspects and finally, transparency and accountability aspects.

Citation patterns within the leading top-tier finance journals implications for journal rankings and other issues

This paper examines all citations and self-citations to a list of 95 finance journals appearing in the Journal of Finance, Journal of Financial Economics and Review of Financial Studies from 1995 through 2005. Additionally, the publication profile of 100 prolific authors in top-tier finance journals is tabulated for these 95 journals. Citations to non-finance journals in economics and accounting are also tabulated for comparison with their finance counterpart along with working papers. Six ranking schemes are constructed with each scheme identifying the top fifty finance journals. Citations to finance journals are highly concentrated within ten journals and similarly for self-citations. Authors of papers appearing in top-tier finance journals pay scant attention to the bulk of research published in other finance journals. Furthermore, these authors cite other economic journals with greater frequency than their counterpart in finance. Of the top fifty finance journals identified in this paper, only 21 are listed in Social Sciences Citation Index (SSCI), and this compares to approximately 500 listed economic journals. Some glaring omissions from SSCI are identified, but most notably the Journal of Applied Corporate Finance, Journal of Financial Research, Journal of Empirical Finance and Journal of Fixed Income. An analysis of 2006 citations patterns is also presented. The top-tier mantra assigned to finance journals has a void with the decision by the Journal of Business to cease publication with the November 2006 issue. This paper identifies five finance journals anyone of which could potentially fill the void.

Developing an ‘as performing’ building assessment

The building profession is increasingly becoming more demanding with respect to building environmental performance. Intentions are to provide best practices into our buildings. In part, this is a response due to the Australian government and other independent organisations that have developed policy on rating tools and performance ranking measures, all with the intention of accomplishing environmentally sustainable buildings.

With rating systems endorsing innovative environmental design solutions, it could be asked: Are our buildings really operating as rated? Do we know whether our designs are in compliance with what was calculated or simulated? Is there a feedback loop informing the design process on successes or failures in our designs or mechanical services?

While ratings continue to focus on ‘by design’ or ‘as built’ rewards, few tools acknowledge perhaps the more crucial bottom line: ‘as performing’. With the exception of an AGBR (Australian Green Building Rating) scheme on actual annual energy consumption, there appears to be no ‘as performing’ assessment. Furthermore, practically every building is a prototype (a one-off) and requires commissioning, programming and scheduling of its services. It would certainly appear that as stakeholders (the procurers, owners, facilities managers and users) of the newly built environment, that what we really want to know is actual on-site confirmation of performance. It is the objective of the Mobile Architecture and Built Environment Laboratory (MABEL), to provide such a service.

The efficiency of improved ranked set sampling methods

Ranked set sampling is a desirable sampling technique where the ranking of the sample observations does not require the actual measurement. This thesis develops new ranked set sampling techniques and determines the sampling characteristics required to best estimate the required population parameters, such as mean and variance.

Central bank independence and governance in the South Asia

This paper constructs the central bank independence and governance (CBIG) index for eight South Asian countries and examines their relationship with inflation. This CBIG index is constructed following the unique model developed by Ahsan, Skully and Wickramanayake (2006). This index consists of total 26 variables; all variables together form the overall index and different sub-sets of these variables construct sub-indices (eg. legal; political; price stability objectives; exchange rate policy; monetary policy and deficit financing; and accountability and transparency).
Several countries have improved their CBIG in last fifteen years. The war torn Afghanistan have established a new central bank act in 2003 which has improved the standard of CBIG in the region. In recent time Nepal has made remarkable improvement in its ranking by allowing improved independence to its central bank. Bangladesh has taken lead in term of gradual CBIG improvement in last fifteen years. Sri Lanka, Indian and Pakistan are three countries always maintained a standard level of CBIG. Bhutan and Maldives showed less improvement among the countries. This paper also examines the statistical relationship between CBIG indices and inflation. The results indicate that there is a positive relationship between CBIG and inflation in the region which in contrary to normal expectation that inflation is one of the robust proxy of actual CBIG.

Prediction of children's flavour preferences. Effect of age and stability in reported preferences

The present study investigated whether children were able to communicate stable flavour preferences and whether mothers’ ability to correctly identify their child's flavour preferences is related to the stability of their child's flavour preferences. On 2 consecutive days, 75 girls and 77 boys (3–10 years, mean age = 7.1 ± 2.3 years) carried out a preference ranking task for five ice-cream flavours: mint, coffee, chocolate and two variants of vanilla. Without input from their child, mothers ranked four of these flavours according to their own understanding of their child's flavour preferences. Spearman rank order correlations suggest that older aged children (5–10 years) have more stable flavour preferences than younger aged children (3–5 years) (p < 0.05). Only 39% of mothers were able to correctly predict children's most preferred flavour, but significantly more parents (61%) were able to predict children's least preferred flavour (p < 0.05). Mothers’ ability to correctly predict their children's least preferred flavour seemed to be facilitated by children's ability to communicate their least preferred flavours in a consistent manner (p < 0.05). It is recommended to apply proper sensory methodologies with children rather than relying on mothers’ report when interested in children's likes. When interested in children's dislikes mothers’ report might be suitable.

Oral sensitivity to fatty acids, food consumption and BMI in human subjects

Fatty acids are the chemical moieties that are thought to stimulate oral nutrient sensors, which detect the fat content of foods. In animals, oral hypersensitivity to fatty acids is associated with decreased fat intake and body weight. The aims of the present study were to investigate oral fatty acid sensitivity, food selection and BMI in human subjects. The study included two parts; study 1 established in thirty-one subjects (29 (sem 1·4) years, 22·8 (sem 0·5) kg/m²) taste thresholds using 3-AFC (3-Alternate Forced Choice Methodology) for oleic, linoleic and lauric acids, and quantified oral lipase activity. During study 2, fifty-four subjects (20 (sem 0·3) years, 21·5 (sem 0·4) kg/m2) were screened for oral fatty acid sensitivity using oleic acid (1·4 mm), and they were defined as hypo- or hypersensitive via triplicate triangle tests. Habitual energy and macronutrient intakes were quantified from 2 d diet records, and BMI was calculated from height and weight. Subjects also completed a fat ranking task using custard containing varying amounts (0, 2, 6 and 10 %) of fat. Study 1 reported median lipase activity as 2 μmol fatty acids/min per l, and detection thresholds for oleic, linoleic and lauric acids were 2·2 (sem 0·1), 1·5 (sem 0·1) and 2·6 (sem 0·3) mm. Study 2 identified twelve hypersensitive subjects, and hypersensitivity was associated with lower energy and fat intakes, lower BMI (P < 0·05) and an increased ability to rank custards based on fat content (P < 0·05). Sensitivity to oleic acid was correlated to performance in the fat ranking task (r 0·4, P < 0·05). These data suggest that oral fatty acid hypersensitivity is associated with lower energy and fat intakes and BMI, and it may serve as a factor that influences fat consumption in human subjects.

Exploring critical success factors for stakeholder management in construction projects

With a focus on different aspects of stakeholder management, various sets of critical success factors (CSFs) have been suggested in the literature. It is crucial to explore the relative importance and groupings of these factors. This paper aims to identify CSFs associated with stakeholder management in construction projects, and explore their ranking and underlying relationship. 15 CSFs were identified through a literature review, and consolidated by interviews and pilot studies with professionals in construction industry. A questionnaire instrument containing these 15 CSFs was sent out to project managers in Hong Kong, and 183 completed questionnaires were retrieved. The top three ranked factors for stakeholder management were "managing stakeholders with social responsibilities", "assessing the stakeholders' needs and constraints to the project", and "communicating with stakeholders properly and frequently". Using factor analysis and considering the high importance of the factor "managing stakeholders with social responsibilities", the 15 CSFs were grouped into five dimensions namely, precondition factor, stakeholder estimation, information inputs, decision making, and sustainable support. All these five groupings and their relationship were included in a framework for successful stakeholder management in construction projects. These findings help to clarify what the high prioritized factors are, and could also be used as an assessment tool to evaluate the performance of stakeholder management and thus help to identify areas for improvement.

Spectral shape descriptor using spherical harmonics

In this paper, we propose a spectral descriptor for shapes of objects. The method relies on transforming the 2D objects into 3D space; distance transform and scale space theory is used to transform objects into 3D space. Spherical harmonics of the voxel grid are used to obtain shape descriptors. The proposed methods are compared against two existing methods which use spherical harmonics for shape based retrieval of images. Comparison is done based on ranking of images which is articulated in recall-precision curves. MPEG-7 Still Images Content Set is used for performing experiments. Experimental results show that the performance of the proposed descriptor is significantly better than other methods in the same category.

Wiki goes to war

Since launching nearly six years ago, Wikipedia has exhibited sustained growth as an internet encyclopaedic resource. Amongst the millions of pages, the 2006 Israel-Lebanon conflict is one of the most revised and popular topics of all, ranking even above the Second World War. Why is this and what do Wikipedia and its daughter project, Wikinews, have to offer history, academia and journalism in their coverage of the Middle East?

ERA distribution of information systems journals

The Excellence in Research for Australia (ERA) initiative being conducted by the Australian Research Council (ARC), mandates a single journal and conference ranking scheme over every academic discipline in Australia. A universal publication outlet ranking list mandated by a government agency is unique and has attracted interest and comment both within Australia and overseas. Equally, the interest shown has come from all sectors involved in academic publishing – authors, reviewers, publishers – and from commercial and open access publishers. This paper investigates the distribution of information systems journals over the various ERA parameters and comments on a claim of bias whereby the ranking of a journal is positively influenced by the number of years it has been in existence in the areas of information systems and business journals. Clear evidence of the diversity of the information systems discipline is observed. The benefits of a multidisciplinary foundation for information systems is also noted. Longer established journals are shown to attract higher rankings and possible reasons for and implications flowing from this are discussed.
